Rika works at a cosmetics store. Though appearing somewhat nervous, she guides the encounter forward with her own unique rhythm. Her sensitive spots seem to always be deep inside, and as her skirt is explored, the most crucial area is eventually reached. Asking to go even deeper, fingers struggle to reach due to her underwear getting in the way. Apparently weak against direct stimulation, the moment fingers are inserted, her breathing quickens uncontrollably, and she can no longer hold back.
